Enum near_vm_errors::VMLogicError

pub enum VMLogicError {
    HostError(HostError),
    ExternalError(AnyError),
    InconsistentStateError(InconsistentStateError),
}

Variants

HostError(HostError)

Errors coming from native Wasm VM.

ExternalError(AnyError)

Type erased error from External trait implementation.

InconsistentStateError(InconsistentStateError)

An error that is caused by an operation on an inconsistent state.

Trait Implementations

impl Debug for VMLogicError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for VMLogicError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for VMLogicError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<HostError> for VMLogicError

fn from(err: HostError) -> Self

Converts to this type from the input type.

impl From<InconsistentStateError> for VMLogicError

fn from(err: InconsistentStateError) -> Self

Converts to this type from the input type.

impl PartialEq<VMLogicError> for VMLogicError

fn eq(&self, other: &VMLogicError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<VMLogicError> for FunctionCallError

Try to convert a general error that happened at the VMLogic level to a FunctionCallError that can be included in a VMOutcome.

VMLogicError have two very different types of errors. Some are just a result from the guest code doing incorrect things, other are bugs in nearcore. The first type can be converted to a FunctionCallError, the other becomes a VMRunnerError instead and must be treated differently.

type Error = VMRunnerError

The type returned in the event of a conversion error.

fn try_from(err: VMLogicError) -> Result<Self, Self::Error>

Performs the conversion.
